RCA DIRECTV PLUS 15407690 - Manual (Page 30)

Final Installation
28 Chapter 3
CAUTION
Use caution when installing,
adjusting or dismantling the
DIRECTV PLUS™ dish and mast.
The weight of the dish may
cause the DIRECTV PLUS™ dish
and mast to swing down and
strike you, a bystander or
nearby objects. This could
cause personal injury or
damage to the dish. Never
insert your fingers inside the
mast. Always grip the mast
around its outside
circumference.
Leveling the Mast
Making sure the mast is plumb and level is one of the most important steps in
installation. If the mast is not plumb and level, the elevation, azimuth, and
polarization settings you get from on-screen instructions will not be accurate. This
makes it difficult to obtain the satellite signal(s).
The mast must be even in both the side-to-side and the front-to-back directions. Side-
to-side leveling determines whether the mounting foot is level. Front-to-back leveling
determines whether the mast is plumb and level.
Leveling Side-to-Side
1. If you mounted the mast on a vertical surface, such as a wall, you leveled the
mast side-to-side when you mounted the mast foot. Skip to “Leveling Front-to-
Back” on the next page.
2. To check whether the mast is level side-to-side, place a carpenter’s level on the
mast as shown in figure A.
3. Is the bubble centered in the level’s window?
If YES — Continue to “Leveling Front-to-Back”.
If NO —
a) If the bubble is not centered, determine which side of the mounting foot
needs to be raised.
b) Unscrew the lag or machine screws from that side of the mounting foot.
c) Place washers between the mounting foot and the mounting surface. Use
enough washers to level the mounting foot.
d) Secure the mounting foot with the lag or machine screws.
Tip
Any hardware store
should have an inexpensive circular
bubble level which can tell you when
the mast is plumb and level in all
directions at once.
STEP 2: Verify that the mast is
level side to side. STEP 3: If the mast is not level, add
washers to level the foot
IMPORTANT
Making sure the mast is plumb
and level is one of the most
important steps in installation.
If the mast is not plumb and
level, the elevation, azimuth,
and polarization settings you
get from on-screen instructions
will not be accurate. This
makes it difficult to obtain the
satellite signal(s).
